We’re proud to announce the release of our Signature Exhaust System for the BMW F8X. After
over a year of research and development, production has begun in house and we will be
shipping systems immediately.
Product features include:


Full 304 Stainless 3.5” mandrel bent piping from the downpipes back
4” 100 cell high flow catalytic converter strategically placed. The cat has been positioned
further towards the rear of the vehicle where exhaust velocity is lower which prevents it
from being restrictive to exhaust flow. The converter helps dial out any raw fuel smell
and also helps smoothen out exhaust pulses for a deeper exhaust note.
The driver side OEM exhaust valve is retained. When the valve is closed all exhaust flow
is routed to a straight through muffler. When the valve is opened the exhaust flow is
allows to pass straight through to the tips.
The Y-Pipe at the rear muffler is a true 3.5” to 3.5” Y, so there is no diameter drop
regardless of whether or not the valve is open, this is especially important for those cars
running high boost levels or upgraded turbos.
Designed and manufactured here in Miami, FL.
Brushed Stainless or Matte Black tips standard. A carbon tip option will be released in
Spring of 2018 as an upgraded option ($350).
15whp peak gain over a stock exhaust. As much as 70ft/lb and 30whp gains at lower
RPMs. Gains will be amplified with higher boost levels.


We believe this to be the most aggressively designed system on the market. It is unparalleled in
both performance and sound and manufactured to our strict standards here at Active
Autowerke.
